OPERATION
(6)
Stop
In any
of
the following statuses, the servo ampuler interrupts and stops the operation
of
the servo
motor:
Refer to Section
3.8,
(2) for the servo motor equipped with electromagnetic brake. Note that
simultaneous
ON
or
simultaneous OFF of stroke end
(LSP,
LSN)
OFF and forward rotation
start
(ST1)
or reverse rotation
start
(ST2) signal has the same stop pattern as described below.
(a) Servo on
(SON)
OFF
The base circuit
is
shut
off
and the servo motor coasts.
(b)
Alarm
occurrence
When an alarm occurs, the base circuit
is
shut
off
and the dynamic brake
is
operated
to
bring the
servo motor
to
a sudden stop.
(c) Forced stop
(EMG)
OFF
The base circuit
is
shut
off
and the dynamic brake
is
operated
to
bring the servo motor
to
a
sudden
stop.
Alarm
A.
E6 occurs.
(d) Stroke end (LSP/LSN)
OFF
The servo motor
is
brought to a sudden stop and servo-locked. The motor may be run
in
the opposite
dwection.
(e) Simultaneous ON
or
simultaneous OFF
of
forward rotation
start
(ST1)
and reverse rotation
start
(ST2) signals
The servo motor
is
decelerated
to
a
stop.
4.2.4
Torque control mode
(1
)
Power on
(a) Switch
off
the servo on
(SON)
signal.
(b)
When main circuit powericontrol circuit power
is
switched on,
"U
(torque command voltage)"
appears on the parameter
unit.
(2)
Test operation
Using
jog operation in the "test operation mode" of the Parameter
unit,
make sure that the servo motor
operates. (Refer to Section 6.8.2.)
(3)
Parameter setting
Set the parameters accordmg
to
the structure and specifications of the machine. Refer to Chapter 5 for
the parameter debtions and to Sections 6.5 for the setting method.
After setting the above parameters, switch power
off
once. Then switch power on again to make the
set parameter values valid.
